Players reported the game hanging for about a second while skating. A
profile showed the memory line in the log walking every heap
(HeapSummary) on the client thread, 0.5 to 2 s every two minutes. An
audit of everything that runs on the game's update and render threads
found more of the same, and Sentry's top crashes had causes of ours.
Freezes:
- Memory log line: no heap walk or thread snapshot; the GPU part and the
write happen on a thread of their own.
- Profile database: synchronous=NORMAL in WAL mode. A save is still kept
when the game crashes; every play event no longer waits for the disk
inside the game's hooks.
- ReSkate's own preferences and values (menu clicks, session sliders,
Discord) are saved by a background writer in order; reads see a value
until it is saved.
- Input: the foreground window and the keyboard are sampled on a thread
of their own (GetAncestor and GetAsyncKeyState stalled the client tick
40-50 ms when another program held Windows' lock); flight input uses
the sample; ClipCursor at most twice a second while a menu has the
pointer.
- Hooks installed while the game runs go in one transaction per place
(HookBatch): throwdowns, remote players, the party, Hall of Meat.
- Off the update thread: the host's map package lookup (one table read in
the background, not the Mods folder per offer), the trainer's map file
and settings save, Board Break's settings save, mod music playlists and
their covers, the Spotify station covers.
- Off the render thread: the Modding page's and the deck card's Mods
folder reads. The overlay's three startup waits share five seconds.
- Less work per frame: Steam names reused while one a frame is asked
again, 2 friends a tick, steam_api64.dll checked once per process,
cosmetic names read in place rather than a system call per character,
an outfit load no longer copies the inventory per slot, the throwdown
type scan runs at background priority over resident memory, the Board
Break deck label is kept a minute.
Crashes:
- Render-resource pool: the metadata fields are written to the state
owner only. The other renderer is 0x2daa00 bytes, and +0x11aae28 is far
past its end (store_field crash; heap corruption in every release).
- Other players' skateboard effects: a stale skateboard component is no
longer followed, and the joint lookup is walked with a bound first (an
endless loop in reused memory ended in GameStall).
- Launcher: Oodle decodes into the buffer it asks for with corrupt data
possible, and its assertions no longer stop the process (heap corruption
in the store-copy scan; a breakpoint in oo2core).
Timings (Send performance timings):
- A frame of half a second or more in a level is sent as game.freeze:
where the time went (ReSkate's tick, the game's frame, or outside it),
whether the renderer kept presenting, and ReSkate's busiest zones.
- Closing the game sends the level session it was in.
Music after a connection drop:
- Spotify device: an account Spotify could not be reached with is kept and
tried again (3 s doubling to a minute); a session that drops is taken
up again. Only an account Spotify refuses is asked for anew.
- YouTube playlist pictures that could not be fetched are tried again,
from 30 s to 10 minutes apart.
Cap outfit packets and stop dropping recipients when a relay cannot be
built. Add per-player relay limits for outfits, skater sound and voice,
and a back-off for Steam IDs that keep failing to join.
Throwdowns: only participants can write rows, turns and scores; a copy
that fails to spawn no longer blocks the others.
Throttle remote skater and skateboard re-creation, cap remote objects
per session, and show developer and friend marks only for identities
Steam vouches for. Route all connections through Steam's relays.
Dedicated server: validate map changes, clean player names, keep vote
cooldowns across reconnects, and cut ban labels on a character boundary.
Skater slot, menu and throwdown fixes; MY MODS rework; lobby parties
Saved skaters (Extension/Customization, Extension/Skater)
- The selected slot, and slots before it, came up as the standard
skater after a start or map change. The game asks for a slot's saved
outfit once per level, and that happened before the cosmetics catalog
could be read. The first selection now waits for the catalog (60 s at
most), and later map changes check against the catalog already read.
- The retry from abdda77 is removed: the record it wrote to is a
temporary on the game's stack, so it could never work.
Pause menu (Extension/UI/NativeMenu)
- ReSkate's entries stopped working after enough map changes: each
level change took new slots in a fixed table of 1024 for the same
buttons. A button now keeps its slot, and a full table hands out the
slot that has gone longest unused.
Throwdowns (Extension/Throwdowns, Runtime/runtime_init.cpp)
- Multiplayer crashed when someone placed a throwdown after a map
change. The event types are freed with the level but were cached for
the process. They are now cleared when a level is left, checked
before use, and looked for again in each level.
MY MODS (Launcher/gui_mods.cpp, gui.cpp)
- Search, a filter and an order; a switch per mod; a menu per row.
- Multi-select with tick boxes, Shift-click and Ctrl+A, and a bar to
enable, disable, move, update or uninstall everything ticked.
Lobby parties (Extension/Multiplayer/Session)
- A lobby is no longer one party. Its host keeps parties the way a
dedicated server does: invite, accept, join, leave, kick, promote,
open and close, with "/p" party chat. The "Lobby party" switch is
gone. Protocol version unchanged (38).
Mod merge (Engine/Vfs), follow-ups to e715b9b
- Files rewritten into the merged patch are tracked by position, so
another mod's added assets no longer shift the lookup.
- Two mods adding different assets under one name is now noted, with
whose copy the maps get.
- mod_merge_unshift_tests compiles with the launcher tests on.
Mesh streaming pool (fixes loading crashes on older GPUs)
- 1.0.0 forced MeshStreaming.PoolSize to 3.5 GiB on every card. An RX 580
crashed while loading with DXGI_ERROR_DEVICE_RESET, and the oversized pool
is the likely cause. The pool is now a quarter of the largest hardware
adapter's dedicated video memory, capped at 3.5 GiB; cards of 6 GB or less
keep the game's own 520 MB. The card, its memory and the chosen size are
logged once at startup.
Remote players (busy servers)
- Transform interpolate is inline plain arithmetic: 22 -> 5.8 ns per joint.
It was 4% of a busy server's client frame, since every player within
200 m has the whole skeleton interpolated every frame.
- Players out of the camera's view and more than 8 m away are sampled at
20 Hz, like far players. Their position still updates every frame for
collision, sound and nametags, and a player coming into view is sampled
that frame.
Expression hooks (run for every expression the game executes)
- No profiler zones in the expression hooks: taking a sample switched them
on, inflating the very samples that measured the hooks.
- The throwdown lab pump does one sorted lookup of the running graph and
skips everything else for graphs it doesn't watch (graph_throttle gets
throttled_graph for this).
Settings and memory reads
- Script gameplay-setting and native-setting gets are served from small
per-thread caches, keyed on the asset/key address, its first 8 name
bytes and a new profile::Store::changes() counter, instead of a store
lookup each call.
- Per-frame reads in the client tick, native settings and population
controls use memory::peek instead of ReadProcessMemory.
- Script error logging probes each argument pointer once.
